![]() The FOIL acronym can help you remember the order in which you should multiply the terms in the binomials. You know the answer is one of those four choices- work backwards and see which one works! You can work backwards using the FOIL method to multiply the two binomials in each answer choice until you find the pair whose product is equal to the trinomial. This is a multiple choice question, so use that to your advantage. However, when working with inequalities, you need to remember to flip the direction of the sign if you multiply or divide by a negative number. Solve inequalities the same way that you solve equations: by isolating the variable on either side of the greater than or less than symbol. Step 3: Now that you know the value of y, you can substitute this value into any equation in the system and solve for x. Substitute this expression for x in the second equation. Step 2: Now you have an expression describing x. ![]() Step 1: Isolate the x variable in the first equation:
